Answer:

7x-1

Step-by-step explanation:

14 + 7x - 15 = k

7x - 1 = k

Finding x,

14 + 7x - 15 = k

=> 14 + 7x = k + 15

=> 7x = k + 15 - 14

=> x = (k + 1)/7

So, 7 * (k+1)/7 - 1 = k

k + 1 - 1 = k

=> k = k

So the answer is true that 7x - 1

Answer:

11.4 feet

Step-by-step explanation:

Applying Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

g² = 9² + 7² = 81 + 49 = 130 ( take the square root of both sides )

g = \sqrt{130} ≈ 11.4 feet

fredd [130]

Answer: 0.9088  

Step-by-step explanation:

Given : \mu=0.30

\sigma=0.045  

Let x be a random available that represents the proportion of students that reads below grade level .

Using z=\dfrac{x-\mu}{\sigma , for x= 0.36 , we have

z=\dfrac{0.36-0.30}{0.045}=1.33333

Using standard normal z-value table,

P-value = P(

P(z [Rounded yo the nearest 4 decimal places.]

Hence, the probability that a second sample would be selected with a proportion less than 0.36 = 0.9088

Solve the system of equations by substitution.
n200080 [17]

Answer:

x = -8

y = -6

Step-by-step explanation:

y = -2x - 22

y = x + 2

x + 2 = -2x - 22

x + 2x = -22 - 2

3x = -24

x = -24 : 3

x= -8

y = -8 + 2

y = -6
